Haven't used HTML/CSS in a few years so I thought I'd take this class to review and then do the interactive one. As when I learned the first time XHTML wasn't covered, I was expecting to have to look this up eventually, but thought the answer would be more clear-cut by now...
In the image lesson the img tag example looks like:
<img src="[image url]"/>
There is a forward-slash there and I wanted to know if this is still being advised. I have read the stackoverflow and old Codecademy forum topics on the subject; the general consensus seems to be to exclude it. However, almost everything I saw is a couple years old, so I was wondering if things have changed since.
